Describe how the Pickering Nuclear Station achieves an excellent record of reliability through its maintenance practices.

The company recognizes the importance of preventive maintenance to the business it is in; this is driven in part by the very large cost of forced power outages. Their maintenance plan involves shutting down the vacuum buildings for inspection at least every 10 years. The firm has well-developed and highly detailed preventive maintenance procedures, which include bringing in an extra 1900 staff members and doing mock-ups of the work area. The process involves the performance of 40,000 tasks.
